Your teacher asks you to prepare 500 mL of a 2.75 molar solution of NaCl for an upcoming
laboratory experiment. Write a step-by-step procedure describing how you would carry out
this task.
Answers
To prepare 500 mL of a 2.75 molar solution of NaCl, measure 80.44 g of NaCl, place it in a 500 mL volumetric flask and fill it with water to the mark.
We'll begin by calculating the number of mole of NaCl in the solution
Volume = 500 mL = 500 / 1000 = 0.5 L Molarity = 2.75 MMole of NaCl =?Mole = Molarity x Volume
Mole of NaCl = 2.75 × 0.5
Mole of NaCl = 1.375 mole
Next, we shall determine the mass of 1.375 mole of NaCl.
Mole of NaCl = 1.375 mole Molar mass of NaCl = 23 + 35.5 = 58.5 g/mol Mass of NaCl =?Mass = mole × molar mass
Mass of NaCl = 1.375 × 58.5
Mass of NaCl = 80.44 g
Therefore, to prepare 500 mL of a 2.75 molar solution of NaCl, measure 80.44 g of NaCl, place it in a 500 mL volumetric flask and fill it with water to the mark.

Which of these challenges is unique to the process of designing prostheses as opposed to engineering other technologies?
- Knowing how a material will fail
- Using the engineering process
- Identifying a need for the technology
- Predicting how a technology will interact with human tissue
Answers
Answer:
predicting how a tech will interact with human tissue.
Explanation:
thats not really common except for in the medical field.
The challenge that is unique to the process of designing prostheses as opposed to engineering other technologies is Predicting how a technology will interact with human tissue. The correct option is option 4.
What is Prosthetic Design?Prosthesis design is typically undertaken by shaping wax on a plaster replica of the patient's anatomy. Realism is predominantly achieved through the prosthetist's ability to interpret the correct location and physically recreate the anatomical shape and detail.
Prosthetic applications are an example of the intersection of design, technology and science.

How many moles are contained in 127 grams of lead?
Answers
Answer:
18.015
Explanation:
Explanation: To convert from grams to moles, you have to use the molar mass provides on the periodic table. The molar mass of lead is 207.2 g/mol. To find the moles, we need to divide the grams of lead by the molar mass. 127/207.2 is equal to about 0.613 moles.

The boiling point of a liquid is tested at 10 different pressures, from 0.5 to 1.4 atmospheres. The results of the tests show that
there is a nearly constant increase in boiling point for each increase in pressure. Which conclusion is reasonable based on this
information? (1 point)
O A boiling point at 1.5 atmospheres could not be predicted with any certainty at all.
O A boiling point at 15 atmospheres could not be predicted with any certainty at all.
O A boiling point at 1.5 atmospheres could be predicted fairly well.
O A boiling point at 15 atmospheres could be predicted fairly well.
Answers
Since the increase in boiling point with increasing pressure is fairly constant, then, the boiling point at 1.5 atmospheres could be predicted fairly well.
We say that a substance has reached its boiling point when its pressure equals the atmospheric pressure. Recall that we can be able to make predictions from the results of an experiment.
In this case, we are told that there is a nearly constant increase in boiling point for each increase in pressure. Therefore, it is reasonable to conclude that, a boiling point at 1.5 atmospheres could be predicted fairly well.

The Universal Space Agency wants to know the results of your Sim investigation. Write your report to the lead chemist, explaining why drops of liquid water appeared on the outside of the cold, but not the warm, soda can. Use evidence from your investigation in your explanation.
Answers
Answer:
due to warm temperature
Explanation:
Explanation:
There is water present in liquid form instead of liquid nitrogen on the outer side of the can because of the temperature present in the surrounding environment. The temperature around the can is little warm which is favourable for the water but not for the liquid nitrogen. The liquid nitrogen present in liquid state when the temperature of the surrounding is too cold. if it is warm, the liquid nitrogen starts boiling and converts into gaseous state so that's why the warmer temperature is responsible for the presence of water not the liquid nitrogen.
17) An ethanol solution has a concentration of 0.500M. What volume in liters of this solution
would contain 8.0 moles of ethanol?
Answers
To calculate the Molar Concentration, we will find the molar concentration by dividing the moles by liters of water used in the solution. For example, the acetic acid here is completely dissolved in 1.25 L of water. Then divide 0.1665 moles by 1.25 L to get the molar concentration, which will be 0.1332 M.
